What is used to disinfect the herbarium?

The conventional disinfection method is mainly sterilization, but it is difficult to kill moths and eggs with non-toxic formula, so formaldehyde fumigation is still a safer method. In foreign countries, the specimen room is sealed and then filled with nitrogen, which is non-toxic, but the specimen room has high structure and high cost. Formaldehyde fumigation is more suitable for China's national conditions, and there is no better operation method in a short time.
